“…Thermodynamic equilibrium analysis using the Gibbs energy minimization method was carried out to explore the migration and transformation of typical ash components in MSW samples at different reaction temperatures during the MSW incineration process, especially for AAEM, chlorine, and silicon. The detailed method for thermodynamic equilibrium analysis is described in the previous studies [24,25]. Moreover, the effect of potential additives on the migration and transformation of AAEM, chlorine, and other elements was systematically studied at a reaction temperature of 900 • C and atmospheric pressure by thermodynamic equilibrium analysis.…”

The formation of slagging and fouling during municipal solid waste (MSW) incineration not only significantly affects heat transfer, but also results in shortened operating cycles. In order to solve the issues, the effect of different additives on the migration and transformation patterns of alkali/alkaline earth metals (AAEM) and chlorine during MSW incineration is screened based on the Gibbs energy minimization method. The effect of potential additives on the ash fusion temperature and combustion reactivity of MSW char is subsequently verified and evaluated by experimental methods. The thermodynamic equilibrium analysis shows that Al(NO3)3, Ca(NO3)2, and Mg(NO3)2 have great potential to increase the ash fusion temperature. The experimental investigation confirms that the addition of Al(NO3)3, Ca(NO3)2, and Mg(NO3)2 significantly increases the ash fusion temperature. The order of increasing the ash fusion temperature by different additives is Mg(NO3)2 > Ca(NO3)2 > Al(NO3)3. The addition of Mg(NO3)2 significantly increased the initial deformation temperature, softening temperature, hemispheric temperature, and flow temperature of ash from 1180, 1190, 1200, and 1240 °C to 1220, 1230, 1240, and 1260 °C, respectively. The addition of Cu(NO3)2, Fe(NO3)3, and KMnO4 significantly decreases the temperature at the maximum weight loss rate of MSW char, while increasing the maximum weight loss rate. Additionally, Cu(NO3)2 shows the best performance in improving the combustion reactivity of MSW char. The addition of Cu(NO3)2 evidently increases the maximum weight loss rate from 0.49 to 0.54% °C−1. Therefore, it is concluded that Mg(NO3)2 and Cu(NO3)2 are supposed to be the most potential candidates for efficient additives. This study presents an efficient and economical method to screen potential additives for alleviating slagging and fouling during MSW incineration.

“…Oliveira et al [10] developed a model for gasification of MSW to evaluate the effect of air, biomass moisture, temperature and pressure on gas compositions and low heating value (LHV) of the outlet gas mixture under adiabatic and isothermal supercritical conditions. Model results indicated that the LHV of the gas mixture along with H 2 and CO concentrations increase with pressure in adiabatic condition while it increases with temperature in isothermal condition.…”
